6.18.2 DE-EMPHASIS SELECT BITS (DE-EMPHX)
Default = 00
00 - Reserved
01 - De-Emphasis for 32 kHz sample rate.
10 - De-Emphasis for 44.1 kHz sample rate.
11 - De-Emphasis for 48 kHz sample rate.
Function:
Used to specify which de-emphasis filter to apply when the “Force PLL Lock (FRC_PLL_LK)” on
page 53 is enabled.
6.18.3 INTERRUPT PIN CONTROL (INTX)
Default = 00
00 - Active high; high output indicates interrupt condition has occurred
01 - Active low, low output indicates an interrupt condition has occurred
10 - Open drain, active low. Requires an external pull-up resistor on the INT pin.
11 - Reserved
Function:
Determines how the interrupt pin (INT) will indicate an interrupt condition.
6.18.4 AUDIO SAMPLE HOLD (HOLDX)
Default = 00
00 - Hold the last valid audio sample
01 - Replace the current audio sample with 00 (mute)
10 - Do not change the received audio sample
11 - Reserved
Function:
Determines how received audio samples are affected when a receiver error occurs.
6.19
Receiver Mode Control 2 (address 1Fh)
6.19.1 TXP MULTIPLEXER (TMUXX)
Default = 000
Function:
Selects which of the eight receiver inputs will be mapped directly to the TXP output pin.
